Answer 2

Let's solve each of these equations step by step:

a) x: 30 = 7 420 : x = 60

In the first equation, x:30 = 7, you can solve for x by multiplying both sides of the equation by 30:

x = 7 * 30 x = 210

In the second equation, 7 420 : x = 60, you can solve for x by dividing both sides of the equation by 60:

7,420 / 60 = x

x = 124

So, the solution to equation a) is x = 210 and x = 124.

b) 7 x y = 490 yx8 = 432

In the first equation, 7xy = 490, you can solve for xy by dividing both sides by 7:

xy = 490 / 7 xy = 70

In the second equation, yx8 = 432, you can solve for yx by dividing both sides by 8:

yx = 432 / 8 yx = 54

So, the solution to equation b) is xy = 70 and yx = 54.

c) z + 250 = 900 825 - z = 600

In the first equation, z + 250 = 900, you can solve for z by subtracting 250 from both sides:

z = 900 - 250 z = 650

In the second equation, 825 - z = 600, you can solve for z by subtracting 825 from both sides:

-z = 600 - 825 -z = -225

Now, multiply both sides by -1 to solve for z:

z = 225

So, the solution to equation c) is z = 650 and z = 225.
